It’s been a really long time. Possibly. Also, possibly a bug or lack of support for test by card. VGA has been around for a really, really long time. Back in the day, I think even my Dads XT 8086 clone was eventually upgraded to VGA. You test best first. If the better test (Vesa, VGA) passes, you stop testing. > > > Happy Hacking, > > David E.
